Synthesis and nonlinear optical properties of new bimetallic iron/palladium complexes
摘要:
Two new ferrocenyl derivatives. (Z)-[1-(benzylthio)-1-(4',4'-dimethyl-oxazolinyl)-2-ferrocenyl]ethylene (3) and (Z)-[1-(benzylsulfino)-1-(4',4'-dimethyloxazolinyl)-2-ferrocenyl]ethylene (4) have been synthesized. On complexation with PdCl2 these yield new bimetallic complexes 5 and 6 respectively. Non-linear optical properties measured by the EFISH technique show an enhanced molecular hyperpolarizability upon complexation. leading to higher values for beta-0.
